VALVE.

SPECIFICATION forming part of Letters Patent No. 373.000, dated November 8, 1887.

Application filed April 25, 1887. Serial No. 236,127. (No model.) Patented in France April 10, 1886, No. 175,393.

To all whom it may concern:

Be it known that we, JEAN ZEHREN and AUGUSTE ZEHREN, lof Paris, France, have inus the 10th day of April, 1886,) of which the' following is a full, clear, and exact description, reference being had to the accom panying drawings, forni-ing part of this specitication,in which- .Figure l is a vertical central section showing the valve locked in its seat. Fig. 2 is a section online 4 4,Fig. l,with the valve closed; and Fig. 3 is a section. on line 3 3, Fig. 2, but with the valve opened.

A is the valvechanlber, B is the valve, and C the valve-rod.

The chamber A has abearing, a, for one end of the valve'rod and an opening, b, for the reception of a stuffing-box that forms the bearing for thel other end. The axis of the'valve is out of center, and through the axis is an opening, c, leading from a housing, d, and in this opening is a plunger, e, which is backed by a spring, j; which is confined in the housing by a screw-cap,`g.

The face ofthe valve B is turned down to fit in the valve-seat h,and on the lower inner portion 0f the chamber is a lug, 2, which has the effect of tipping the valve as it is lifted out of its seat,while another,lug 1,prevents the valve from making more than a half-revolution.

The valve-rod C has intermediate bearings in yokes E, that project from the valve, and these yokes are shouldered,as at E,to receive a web, F, that is formed on or attached to the Valve-rod C, which web also serves to lock the valve in its seat.

The operation of our device is as follows: The valve is closed by turning the valve-rod until its web strikes the plunger e, and when this occurs the valve will be carried to a vertical position, as in dotted lines, Fig. 2and then as the rod is further turned its web, acting against the head of the plunger, will lock the valve tightly in its seat. To open the valve, it is only necessary to turn the valve-rod back, when the web, striking the shoulders E', will lift the valve from its seat, when the pressure in the pipe willturn itinto the position shown in Fig. 3.

The valve is equally uscfuliu steam, gas, or water pipes.

Having now fully described our invention, whatwe claim as'new', and desire to secure by Letters Patent., is-

A valve hung ecceutrically in its chamber, in combination with a webbedV valve-rod located in its rear,a valve having a plunger projecting through it to engage'with a web of the valve-rod as the valve is locked to its seat, and yokes through which the valve-rod passes,said yokes having shoulders with which the web of the valve-rod engages to unlock the valve, as set forth.

In witness whereof we have hereunto signed our names in the presence of two subscribing witnesses.
